The best approach for selecting controls to minimize risk is to perform a risk assessment. A risk assessment is a process that identifies, analyzes, and evaluates the risks that could affect the organization's objectives or operations. A risk assessment helps to determine the likelihood and impact of the risks, and to prioritize them based on their severity and relevance. A risk assessment also helps to select the most appropriate and effective controls to minimize the risks, such as avoiding, reducing, transferring, or accepting the risks. A risk assessment is the best approach for selecting controls, because it helps to align the controls with the organization's risk profile, risk appetite, and risk objectives, and to ensure that the controls are adequate, suitable, and cost-effective. The other options are not the best approach for selecting controls, although they may be part of or derived from the risk assessment. Industry best practice review, cost-benefit analysis, and control-effectiveness evaluation are all activities that can help to support or improve the control selection, but they are not the best approach for selecting controls.
